with said conveyor belts, drying said sheets as they are passing oversaid conveyor belts,

and, nearthe-point Where they are to be delivered, giving to said sheetsan accelerated motionin' order togive to said sheets an 1m- 1 petus sothatth'ey will quickly fallin position at the point of delivery, say theyogger box. The conveyor belts are made of metal to keep the heatfrominjuring them, and for the purpose of keeping same in a normal conditionat-all times.

The operation above described is used 111 connection with printed sheetswhich have a margin on each side thereof. \Vhen no mar-- gin ispresenton the printed sheets, andes- I pec ially whenthey are heavily printed,I employ a star wheelmechzinismyhaving small points which assist infeeding the printed sheets, at the point where the accelerated motion isdesired-,the points being so small that none or very little impressionwill be made upon the inked sheet, as to disfigure or smear the same.

The-advantages and features of my invention will readily become apparentfrom readingthe following specification.

It will be understood that my device obviates the necessity of racking"the paper or slip-sheeting the same.

In the accompanying drawing, forming:

journaled in oneend-of the links- 3 1, the

and

the shaft 5.

. Fig-1, isa plan view of theattachmentj Fig. 10, is a central sectionthrough Fig. 9.

The attachment is used as before stated, in connection wlth printingpresses and carries off the printed sheet to a delivery point; the

printing press not being shown, except the drive wheel 1, mounted on ashaft 2 of the sald printing press. A belt?) leads from pulley 1 tothelarge pulley 1, mountedon a stud shaft 5, which is mounted in a framemade upof sides 6 and7, and stay bars 8.

At the front of the attachment, mounted in frames 6 and 7, I provide apulley shaft Stand at the rear a pulley shaft 1O.

Securely mounted to these shafts 9 and 10 are the sprocket wheels 12;thesesprocket wheels engage with the sprocket chains (conveyor chains)13, which pass over the said sprocket wheels 12.

The pulley shaft 10 is revolved by means of the belt pulley 14- which issecurely mounted thereon, a belt 15 passing over pulley 14,

and adjustable pulley 16, which pulley is mounted on a shaft 17,1nountedinside frameG. A'belt 18 also'passes over the ad- Justable conepulley-16 and another cone pulley 19; this cone pulley 19v ismounted onIt willbe seen that when the belt 3 is put into operation by the pulley1, the pulleys 4 and 19 being integral, will operate the belt 18, whichin turn operates the belt 15 through medium of pulley 16, the belt 15then revolving the pulley 1 1, which ais securely mounted to the shaft10, will in turn revolve said shaft, causing the conveyor chains 13 tooperate over the sprocket wheels 12-. 1 By this means the conveyor beltsare operated and forced to travel-likean endless belt, carrying theprinted sheets, which are deposited upon them, to their destination. 7 j

On the shaft 5, I mounta pulley 20 over which passes a belt 21, whichbelt also passes over the pulley 22, which is-securely mounted on ashaft 23. This shaft has its hearings inthe side extending arms21 whichare fastened atthepoints' 25 to the side frames 6 and 7.

'Acljus-tablymounted on shaft 23 are the feedrolls 26, 27, 28, 29 and30. The feed rolls 26 and30 engage with upperfeed rolls 31 and 32 whichimpart motion through 7 frictionalcontact. These rolls 31 and-32' areadjustablymountedon'a-shaft 38, which is other ends of said links beingadj ustably mounted on the shaft 35; this shaft is mounted in thebearing plates 36 which are secured to the side extending arms 2i (seeparticularly Figs. 1 and 2).

iiil'iustably mounted on the shaft- 33, I provide the star teed wheels2-37. This ad justinent or a lateral nature in order to cover variouswidths of printed sheets. The links ill being pivotally mounted on theshat. allows an up and down motion to accommodate the thickness oi thepaper. in order to adjust the links 3-; laterally, 1 provide anadjusting clamp :38 and thuml'i screw Iii). liy operating screw 39 theclamp can be loosened or lightened and the links Iii can thus be movedto any position de sired and held there by reason oi slot. .10 in theclamp.

lit the star wheels 3? are not needed, they may be moved over out of theway by removing them from the attachment and when needed again they canbe put back into position on account of their iuljustability on shaft53.

in the tie bars 8, brackets 41, which are guides the guides beingl'ormed angular in shape and have :lorwardly extending lingers all; toguide the paper to its limit of travel, at which time the sheets tail onthe table it in the jogger box 15.

The lower tteed roll 52C) engages the roll 3 and the roll engages theroll 32, the rolls 26 and 30 being the drivers and the rolls 31 and 32being driven.

1' provide a number of heaters, in the present instance, two are shown.In the present instance they are made up of a. tube section of pipe 46,provided with a multilicit v ot holes i? and are mounted in the sideframes (3 and 7. 1i? I. desire to heat by electricity 1 use anelectrical heating unit 4-8, shown in Figs. 5 and (S. The sheets ofpaper (printed) are dried as they pass over the healing devices.

The star wheels 37 are formed of a disc part i9 and have a hub securedto the shal'i 33 by set screws 51, and have at their periphery a largenumber of thin teeth 52, the teeth being formed or a knife-like edge,see Fig. 10, being, however, not pointed but slightly flattened on theiredge. Two wings or brackets as 53 are shown for securing the attachmentto the printing press.

In order to operate on margin, the rolls ill. and 232 are brought intocontact with the drive rolls 2'7 and 12%.) see Fig. el, these rollshaving a flat sur'taee :lace can be used when the delivery is made onthe margin, the .roll Elli merely acting as a sup 'iorting roll. Therolls 31 and 32 travel on the margin, but when no margin is present,then the star wheels Eli are brought into play, and they teed the sheetsby contact with the prints 52.

l: mount adjustable :lasiened to the side The star wheels 37 arepreferably adjusted to the inside of the lower rolls 27 and .29, whichallows the paper to buckle or wave as the star wheel teeth pass downwardly and draw the paper over the lower rolls, see Fig. 3.

The printed sheet is marked 60, and in Fig. -i, it is shown marginallyfed, and in Fig. 3, where no margin is present said sheet (50 is beingted by the star wheels 37 and i! will be seen in this figure that theprinted sheet (it) is somewhat waved or buckled, as hereioikue stated,to give a proper contact for the star wheels with the printed sheets.

ilhrough the system cl? cone pulleys, belts, and different diameter ol?pulleys, 1 am enabled to operate the conveyor chain at any speedrequired, and to increase or diminish the same according to the size ofthe sheet which being printed, and through this nuans l am a lro enabledto speed the shaft which carries the feed rolls and the star wheels to agreater or less extent, and to operate the same taster than the sheetsare conveyed in order to quickly precipitate said sheets into the joggerbox or other suitable point of delivery.

The printing press to which this attachment is preferably applied, is,as before stated, one which has a constantly operating shatt :2 with apulley 1. thereon, as this shaft and pulley continue to operate whenthis prii'iting press automatically steps or is manually stopped untilall the sheets which have been printed, before stop nige, will bedelivered properly, thus preventing the waste of any of the printedmatter and preventing the same from taking fire by reason of anystoppage of the conveyors, thus saving the printed sheets and preventingloss.

If this attachment is attached to a printing press of another character,I may use a sn'iall motor to run and operate the same, and then continueto operate the same after the printing press has stopped, or, itdesired, during the operation of the press, just as I see fit.

Vi hen the attachment is operated separately and independently of theprinting press, or operated ten'iporarily when the printing press forany reason stops, I provide a motor as shown in Fig. 2.

The construction and term herein shown is a preferred way of making myattachment, but I may deviate therefrom and have the construction tosome extent and may also alter the same without departing from theprinciple of the invention, when attached to a printing press of adifferent construction than the one to which it may be applied.
